Generate a detailed pixel art character of Mabel Wakefield, a 19-year-old woman with a profound backstory of resilience and transformation. Mabel has emerged from a year-long imprisonment in the Alderwood Dungeon, visually transformed by her ordeal. Her appearance should reflect a juxtaposition of despair and determination: long, unkempt brown hair, a once-simple dress now tattered and stained, evolving into attire that symbolizes her growth into a resilient warrior.
